Riesz transforms through reverse Hölder and Poincaré inequalities

Frédéric Bernicot, Dorothee Frey

We study the boundedness of Riesz transforms in $L^{p}$ for $p > 2$ on a doubling metric measure space endowed with a gradient operator and an injective, $ω$ -accretive operator $L$ sat…

Paraproducts via $H^{\infty}$ -functional calculus

Dorothee Frey

Let $X$ be a space of homogeneous type and let $L$ be a sectorial operator with bounded holomorphic functional calculus on $L^{2} (X)$ . We assume that the semigroup $\{e^{-tL}\}_{t>0}…
